An air traffic controllers strike in France is likely to impact on Irish passengers planning to fly to France, or over French airspace.

Ryanair has cancelled 26 flights to and from France due to the action.

Aer Lingus says it currently plans to operate its full schedule, but is warning that customers can expect delays to some flights.

The Chief Marketing Officer with Ryanair, Kenny Jacobs, says intending passenger should check with their airlines before travelling to the airport;

The action, starting today, is expected to last for six days. Last night, French authorities were still trying to assess the likely impact.

Airports in the UK say the industrial action is likely to affect many of their flights using French airspace including those to Spain.

Cancellations and delays may be significant but are not expected to be as bad as first feared. One of the two French unions involved called off its action after talks.
